Rotary spindle structure
Abstract
A rotary spindle structure applied in a housing is provided,
which includes two spindle lugs having a suspended resilient butt
joint respectively. When a spindle rod is fit in the spindle lugs,
both end faces of the spindle rod bear against the resilient butt
joints, so that the resilient butt joints are forced to expand
outwards till a pivot hole of the spindle rod is snapped with
protruding walls of the spindle lugs, and thus, the spindle rod is
freely rotationally connected to the spindle lugs. Furthermore, a
pair of reinforcing pads is used to bear against the resilient butt
joints to enhance the joining strength between the spindle lugs and
the spindle rod.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This non-provisional application claims priority under 35
U.S.C. .sctn. 119(a) on Patent Application No(s). 095201391 filed
in Taiwan, R.O.C. on Jan. 20, 2006, the entire contents of which
are hereby incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of Invention
[0003] The present invention relates to a rotary spindle structure,
and more particularly to a rotary spindle structure, which is
easily assembled and disassembled, and not easily deformed.
[0004] 2. Related Art
[0005] Concerning portable electronic products in the current
market, due to the rapid development of electronic science and
technology, wireless communication has become the mainstream of the
current electronic industry, in order to transmit and exchange
information more rapidly and efficiently. A directional antenna for
receiving wireless signals becomes an important electronic device.
In order to receive more signals with more complete contents, the
antenna is designed to be capable of swinging freely, such that a
user can randomly adjust the direction and tilt angle of the
antenna, so as to improve the efficiency of the antenna in
receiving signals.
[0006] In Taiwan Patent No. M266562 disclosed "Pivotal Body
Buckling Structure with Positioning Adjustability", and Taiwan
Patent No. No. M282472 disclosed "Gyrating Structure of Rotation
spindle", an adjustable rotation spindle is disclosed to be applied
in various products required to be rotated and enfolded, and some
elements such as a resilient element, a snap ring, and a protruding
rib of the body of the rotation spindle, are used for fixing and
snapping the rotation spindle.
[0007] However, the component elements for a conventional spindle
structure are so complex that the assembling steps and the
manufacturing time are increased, which results in a high cost.
Furthermore, in most cases, the rotary spindle structure is made of
plastic and cannot be easily assembled and disassembled because of
the poor material strength, and the rotary spindle structure will
suffer from plastic deformation after a long time use, which causes
the changing of the size, thereby affecting the service life. On
the contrary, if the material strength of the rotary spindle
structure is enhanced, the user will find that it is difficult to
assemble and disassemble the rotary spindle structure and the
rotary spindle structure is usually damaged due to inappropriately
exerting a force. Additionally, in order to facilitate the
installation, the contact area of the spindle lugs is increased
accordingly, and thus, the spindle lugs become higher, which not
only occupies a larger space, but also causes a poorer appearance
and a higher manufacturing cost.
SUMMARY OF THE INVENTION
[0008] In view of the aforementioned problems, the present
invention provides a rotary spindle structure, so as to eliminate
the limitations or disadvantages in the prior art that the material
strength and the convenience in installation cannot be considered
at the same time.
[0009] The present invention provides a rotary spindle structure,
which is applied in a housing. A pair of suspended resilient butt
joints is disposed on a pair of spindle lugs of the rotary spindle
structure, and a spindle rod is pivotally fit in the spindle lugs.
When the spindle rod is fit in the spindle lugs, both end faces of
the spindle rod bear against the resilient butt joints to force the
resilient butt joints to expand outwards till pivot holes of the
spindle rod are snapped with protruding walls of the spindle lugs,
and thus, the spindle rod is freely rotationally connected to the
spindle lugs. The resilient butt joints enable the user to easily
fit the spindle rod in the spindle lugs, without exerting excessive
forces.
[0010] Additionally, a pair of reinforcing pads is disposed on the
side of the housing opposite to the side where the spindle lugs are
disposed, and bears against one side of the resilient butt joints.
The joining strength between the spindle slugs and the spindle rod
can be enhanced through using a pad instead of other complicated
elements. Thus, the aims of elegant appearance and
cost-effectiveness can be both achieved without increasing the
height of the spindle lugs.
[0011] Further scope of applicability of the present invention will
become apparent from the detailed description given hereinafter.
However, it should be understood that the detailed description and
specific examples, while indicating preferred embodiments of the
invention, are given by way of illustration only, since various
changes and modifications within the spirit and scope of the
invention will become apparent to those skilled in the art from
this detailed description.

DETAILED DESCRIPTION OF THE INVENTION
[0018] Refer to FIGS. 1A and 1B, the present invention provides a
rotary spindle structure 100, which is applied in a housing 200.
The rotary spindle structure 100 has a pair of spindle lugs 110 and
a spindle rod 120. The spindle lugs 110 are disposed oppositely on
one side of the housing 200 and spaced apart by a distance, and
each of the spindle lugs 110 has a suspended resilient butt joint
111 with a corresponding protruding wall 112 respectively. The
spindle rod 120 is just pivotally fit in the spindle lugs 110 and
has two end faces, which are opposite to each other and have a
corresponding pivot hole 121 respectively. When the spindle rod 120
is fit in the two spindle lugs 110, the two end faces of the
spindle rod 120 bear against the resilient butt joints 111, so that
the two resilient butt joints 111 are forced to expand outwards
till their protruding walls 112 are snapped with the pivot holes
121 of the spindle rod 120, and thus, the spindle rod 120 is freely
rotationally connected to the spindle lugs 110.
[0019] As shown in FIG. 1B, the spindle rod 120 further has at
least one stopper 122 to limit the rotation of the spindle rod 120
within a specific range.
[0020] Please refer to FIG. 2A, FIG. 2B, and FIG. 2C, another
embodiment of the present invention mainly provides a rotary
spindle structure 100, which is applied in a housing 200. The
rotary spindle structure 100 has a pair of spindle lugs 110, a
spindle rod 120, and a pair of reinforcing pads 130. The spindle
lugs 110 are disposed oppositely on one side of the housing 200 and
spaced apart by a distance, and each of the spindle lugs 110 has a
suspended resilient butt joint 111 with a corresponding protruding
wall 112 respectively. The spindle rod 120 is just pivotally fit in
the spindle lugs 110 and has two end faces, which are opposite to
each other and have a corresponding pivot hole 121 respectively.
When the spindle rod 120 is fit in the spindle lugs 110, the two
end faces of the spindle rod 120 bear against the resilient butt
joints 111, so that the two resilient butt joints 111 are forced to
expand outwards till their protruding walls 112 are snapped with
the pivot holes 121 of the spindle rod 120, and thus the spindle
rod 120 is freely rotationally connected to the spindle lugs 110.
The reinforcing pads 130 are disposed on one side of the housing
200 opposite to the side where the spindle lugs 110 are disposed,
and bear against one side of the resilient butt joints 111, so as
to enhance the joining strength between the spindle lugs 110 and
the spindle rod 120.
[0021] As shown in FIG. 2B, the spindle rod 120 further has a
stopper 122 to limit the rotation of the spindle rod 120 within a
specific range. Additionally, the contact surface for the
reinforcing pads 130 to bear against the resilient butt joints 111
is a ramp.
[0022] The invention being thus described, it will be obvious that
the same may be varied in many ways. Such variations are not to be
regarded as a departure from the spirit and scope of the invention,
and all such modifications as would be obvious to one skilled in
the art are intended to be included within the scope of the
following claims.
